OLFACTION TASTE AND COGNITION

Olfaction and cognition in schizophrenia: sex matters.

Cognitive and olfactory deficits occur in schizophrenia, but little is known whether sex modifies these deficits. We examined the relationship between olfaction and cognition in 55 schizophrenia patients and 32 healthy controls. Patients and controls demonstrated significant differences performing cognitive tasks. In patients, sex modified all relationships of odor identification to cognition. ...

The Physics and Biology of Olfaction and Taste

Traditionally, the chemical senses include olfaction and gustation: olfaction (smell) reports on gaseous substances carried by air over long distances, and gustation (taste) provides information about food material already in the mouth. However, in recent times behavioral, physiological, histological, and molecular studies have increased our understanding of vertebrate chemoreception, and four ...

Receptor cell regeneration and connectivity in olfaction and taste.

The capacity of adult mammalian gustatory and olfactory receptor cells to regenerate and make synaptic reconnections provides examples that may be useful in initiating replacement of other kinds of sensory receptor cells. The sensory code for taste quality may not be degraded by taste receptor cell turnover because axons probably recouple to the appropriate type of new receptor cell by axon-rec...

The 15th International Symposium on Olfaction and Taste.

INTERNATIONAL SYMPOSIUM ON OLFACTION AND TASTE Perceptual and Neural Pliability of Odor Objects

A key function of the sense of smell is to guide organisms towards rewards and away from dangers. However, because relatively few volatile chemicals in the environment carry intrinsic biological value, the meaning of an odor often needs to be acquired through learning and experience. The tremendous perceptual and neural plasticity of the olfactory system provides a design that is ideal for the ...
